Sydney Trains Video #57 - VVVF Motor Compilation Remastered 

pin me, i am biggest fan

the gear growl of the camshaft V sets and the reds is addictive

I really like it

The Mariyung D Set has basically identical traction motors to the Nippon Sharyo Highliner II BiLevel EMUs

Great video! I really love the sound from the train motors. However, I agree with Thomas. VVVF is a kind of drive that changes DC to AC which has variable-voltage and variable-frequency. The output voltage of chopper module is a kind of pulse which has changable width(means changable average voltage) controlled by periodic opening and closing of the switches(such as GTOs) used in the chopper, and after the filter it becomes changable DC voltage. Therefore, we can find that voltage and frequency never change in a chopper module. In a word, I hold the view that chopper is absolutely not a kind of VVVF🤣If there is anything wrong, I would appreciate that someone points it out!!

I like it so much thanks

Nice!

I like the h sets sound the best

Please remember: that T-Set C-Set K-Set & S-Set is non AC motor trains, VVVF only use for AC motor trains, including the A/B-Set D-Set M-Set H-Set & Alstom Metropolis.

so cool

Fecha de los comicios Gracias a las fuerzas 🥰🎉🎊🥳

High platform in the stations, as in UK?

M, metro and d set have a simular sound

Jeper

D sets have Mitsubishi SiC
